Red-crested Bustard
Lophotis ruficrista
A medium-sized, black-bellied bustard with diagnostic white chevrons on a brown-and-black mottled back. The male has a brown-gray neck and slaty cap, and the female is plainer. The name is misleading, as the red crest is almost always hidden. It walks slowly and steadily in arid woodlands, where it is common but due to its camouflage often avoids detection. The song is a sequence of clicking “tic-tic” notes that are followed by a mournful piping “sweee-swee-sweee sweet” series that accelerates to a crescendo. The male indulges in an absurd display in which he flies nearly vertically into the sky and then folds his wings and somersaults down as if shot, only to unbelievably land on his feet. In flight the Red-crested Bustard’s all-black underwings differentiate it from Black-bellied Bustard, which has white windows in the underwing.

分类信息
One syntype specimen of Otis ruficrista Smith (Rep. Exped. Centr. Afr., 1836, p.56.) is held in the collections of National Museums Liverpool at World Museum, with accession number D56 (male adult). The specimen was collected in the “Country between Latakoo and the Tropic of Capricorn”, South Africa by Andrew Smith. The specimen was purchased at the sale of Smith’s South Africa Museum (Lot 89, 6 June 1838) and came to the Liverpool national collection via the 13th Earl of Derby’s collection which was bequeathed to the people of Liverpool in 1851. There is a further syntype specimen in the bird collection at the Natural History Museum at Tring.

Scaly Laughingthrush
Trochalopteron subunicolor
Dark golden-brown laughingthrush with extensive black-edged scaling all over its body. Wings are paler, brighter yellow, with slight blue-gray highlights toward the tip. Somewhat similar to Blue-winged Laughingthrush, but that species is browner, with a much broader blue wing panel and a narrow black eyebrow. Scaly Laughingthrush forages on the ground and in undergrowth, often in pairs.
Abyssinian Longclaw
Macronyx flavicollis
A large and relatively colorful member of the pipit family. Note the black necklace, orange throat, and partially yellow eye-stripe. The white corners of the black tail are conspicuous during the weak, fluttering flight. Found on the ground in montane grassland, often in wet areas. Brownish immatures can be confused with pipits, but are larger and more robust. The vocalizations include “tsik” calls and whistles.
Dull-capped Attila
Attila bolivianus
Big-headed flycatcher of humid rainforest midstory. Rich red-brown with a slightly grayer head and pale eye. Perches with upright posture and appears rather stocky, with a short tail, large head, and heavy bill. Pale eye and fairly dark plumage help distinguish it from other attilas, as does voice. Listen for a rising series of whistles, usually finished with a lower note: “weer, weer, weer, weer, woo”; sounds melancholy, without the upbeat, double-syllable note phrasing of Bright-rumped Attila.
